This book was released on 1991 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the work on experimental research in intermediate energy nuclear physics carried out at New Mexico State University in 1991 under a great from the US Department of Energy. Most of these studies have involved investigations of various pion-nucleus interactions. The work has been carried out both with the LAMPF accelerator at the Los Alamos National Laboratory and with the cyclotron at the Paul Scherrer Institute (PSI) near Zurich, Switzerland. Part of the experimental work involves measurements of new data on double-charge-exchange scattering, using facilities at LAMPF which we helped modify, and on pion absorption, using a new detector system at PSI that covers nearly the full solid-angle region which we helped construct. Other work involved preparation for future experiments using polarized nuclear targets and a new high-resolution spectrometer system for detecting [pi]° mesons. We also presented several proposals for works to be done in future years, involving studies related to pi-mesonic atoms, fundamental pion-nucleon interactions, studies of the difference between charged and neutral pion interactions with the nucleon, studies of the isospin structure of pion-nucleus interactions, and pion scattering from polarized 3He targets. This work is aimed at improving our understanding of the pion-nucleon interaction, of the pion-nucleus interaction mechanism, and of nuclear structure.

This book was released on 1992 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes investigations of various pion-nucleus interactions and nucleon-nucleus charge-exchange reactions. The work was carried out with the LAMPF accelerator at the Los Alamos National Laboratory and the cyclotrons at the Paul Scherrer Institute (PSI) near Zurich, Switzerland, and at Indiana University (IUCF), as a collaborative effort among several laboratories and universities. The experimental activity at LAMPF involved measurements of new data on pion double-charge-exchange scattering, some initial work on a new Neutral Meson Spectrometer system, a search for deeply-bound pionic atoms, measurements of elastic scattering, and studies of the (n, p) reaction on various nuclei. At PSI measurements of pion quasielastic scattering were carried out, with detection of the recoil proton. Work on the analysis of data from a previous experiment at PSI on pion absorption in nuclei was continued. This experiment involved using a detector system that covered nearly the full solid angle.

This book was released on 1990 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the work on experimental research in intermediate energy nuclear and particle physics carried out by New Mexico State University in 1988--91. Most of these studies have involved investigations of neutron-proton and pion-nucleus interactions. The neutron-proton research is part of a program of studies of interactions between polarized nucleons that we have been involved with for more than ten years. Its purpose has been to help complete the determination of the full set of ten complex nucleon-nucleon amplitudes at energies up to 800 MeV, as well as to continue investigating the possibility of the existence of dibaryon resonances. The give complex isospin-one amplitudes have been fairly well determined, partly as a result of this work. Our work in this period has involved measurements and analysis of data on elastic scattering and total cross sections for polarized neutrons on polarized protons. The pion-nucleus research continues our studies of this interaction in regions where it has not been well explored. One set of experiments includes studies of pion elastic and double-charge-exchange scattering at energies between 300 and 550 MeV, where our data is unique. Another involves elastic and single-charge-exchange scattering of pions from polarized nuclear targets, a new field of research which will give the first extensive set of information on spin-dependent pion-nucleus amplitudes. Still another involves the first set of detailed studies of the kinematic correlations among particles emitted following pion absorption in nuclei.

Progress Report, April 1, 1994--March 31, 1997 written by and published by . This book was released on 1996 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the work on experimental research in intermediate energy nuclear physics carried out by New Mexico State University from April 1, 1994, through March 31, 1996 under a grant from the US Department of Energy. During this period we began phasing out our programs of study of pion-nucleus and pion-nucleon interaction and of nucleon-nucleus charge-exchange reactions, which have been our major focus of the past two or three years. At the same time we continued moving in a new direction of research on studies of the internal structure of nucleons and nuclei in terms of quarks and gluons. The pion and nucleon work has been aimed at improving our understanding of the nature of pion and proton interactions in the nuclear medium and of various aspects of nuclear structure. The studies of the quark-gluon structure of nucleons are aimed at clarifying such problems as the nature of the quark sea and the relation of the nucleon spin to the spins of the quarks within the nucleon, questions which are of a very fundamental nature.

This book was released on 1995-02-17 with total page 882 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main goals of intermediate energy nuclear physics, which serves an important role as a bridge between nuclear and particle physics, is to construct the theory of strong interaction phenomena in terms of conventional degrees of freedom (nucleons, deltas and mesons) as well as of quark degrees of freedom.The main topics to be discussed at this conference are the interaction of pions and other mesons with nuclei at intermediate energies and the role of mesonic degrees of freedom in nuclear reactions, including photon, hadron and heavy ion induced reactions. Both theoretical and experimental results will be included.Over the past two decades, the Meson Factories, including LAMPF, TRIUMF, and PSI, have provided us with systematic experimental information on hadron-hadron and hadron-nucleus dynamics. Major accelerators of JINR are also suitable for studying problems in Intermediate Energy Nuclear Physics. At the present time, first experiments have been performed with the proton beams at the Moscow Meson Factory of INR. One of the purposes of this conference is to introduce the intermediate-energy physics community to the possibility of utilizing the facilities of JINR and INR during the next decade.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this thesis is to present new experimental information about modifications to the pion-nucleon single charge exchange interaction, [pi][sup +]n [yields][pi][sup 0] p or [pi][sup [minus]] p [yields] [pi][sup 0]n, due to the presence of other nucleons. The results of two experimental studies of pion single charge exchange in the three nucleon system near the [triangle]-resonance are presented. Both of these experiments were performed at the Clinton P. Anderson Meson Physics Facility (LAMPF), a division of the Los Alamos National Laboratory. Each explored different aspects of pion single charge exchange in three body nuclei--[sup 3]He and [sup 3]H. Since the nuclear wavefunctions of the three nucleon systems are believed to be well understood, it should be possible to perform theoretical calculations of pion interactions with this system and compare their predictions with the experimental results.

Available in PDF, EPUB and Kindle. Book excerpt: We report on scattering and reaction experiments on light nuclei using the [pi]-meson and proton beams from the Los Alamos Meson Physics Facility (LAMPF) and the Indiana University Cyclotron Facility (IUCF). Differential cross sections, cross section asymmetries, and angular correlation functions have been measured in order to test models of the reaction mechanism and of nuclear structure. At LAMPF we have measured asymmetries for pion scattering from polarized [sup 13]C which are uniquely sensitive to the isoscalar spin density. In order to determine details of the reaction mechanism, we have obtained approval for a scattering experiment on polarized [sup 3]He for which the nuclear structure is very well known. We have completed data taking for two studies of elastic scattering of [pi][sup +] from [sup 6]Li and [sup l3]C. The detailed differential cross sections from these experiments will be used to constrain theoretical analyses of previous polarization experiments done at the Pierre-Scherrer-Institute (PSI) and at LAMPF. We have analyzed [pi]-triton coincidence events from the [sup 4]He([pi], [pi][prime] t)p reaction and have found evidence for direct triton knockout from [sup 4]He. We have extended these angular correlation measurements to higher energies and to [sup 2]H and [sup 3]He targets. At IUCF we have performed the first [sup 4]He(p, n) experiment at intermediate energies, T[sub p] = 100, 147, and 200 MeV, in a search for previously reported narrow states in [sup 4]Li of widths of [approx] 1 MeV. Within the statistics of the data we have found no evidence for such narrow structures.

Available in PDF, EPUB and Kindle. Book excerpt: With the availability of intense beams of greatly improved energy resolution from LAMPF, interest in intermediate energy nuclear physics is at a high level. A major interest of the Oregon State University group is the study of elastic and inelastic scattering of pions from nuclei. Since pions exhibit several features not shared by low-energy nuclear projectiles they are especially interesting objects with which to probe nuclear structure in scattering experiments. This report contains a summary of instrumentation projects, and results from the experimental programs.

Book Synopsis Intermediate-Energy Nuclear Physics by : A. S. Iljinov
Download or read book Intermediate-Energy Nuclear Physics written by A. S. Iljinov and published by CRC Press. This book was released on 1994-01-27 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intermediate-Energy Nuclear Physics is devoted to discussing the interaction between hadrons with nuclei, which leads to the emission of particles during an intranuclear cascade and subsequent decay of a highly excited residual nucleus. Experimental data and the methods and results of the calculation of probabilities of various processes initiated by intermediate-energy hadrons in nuclei are set forth and discussed. The potential for obtaining information on the structure and properties of nuclei by comparing experimental data with theoretical results is analyzed. New issues, such as analytic methods for the solution of kinetic equations describing the cascade, nuclear absorption of hadrons from bound states of hadronic atoms, interaction of antinucleons with nuclei, multifragmentation of highly excited residual nuclei, and polarization phenomena, are discussed in detail. The book also demonstrates hadron-nucleus interactions that bridge the gap between low-energy and heavy ions physics. It is an interesting reference for nuclear physicists and other researchers interested in the analysis of problems associated with the evolution of the early (hot) universe, neutron stars and supernovas, after-burning of radioactive waste in nuclear energy installations, and electronuclear energy breeding.
